Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 124,124,425, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 124,124,425 | |
| -1 | -124,124,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 124,124,425.
Example:
1 x 124,124,425 = 124,124,425
and
-1 x -124,124,425 = 124,124,425
Notice both answers equal 124,124,425
With that explanation out of the way, let's continue. Next, we take the number 124,124,425 and divide it by 2:
124,124,425 ÷ 2 = 62,062,212.5
If the quotient is a whole number, then 2 and 62,062,212.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 124,124,425 | |
| -1 | -124,124,425 |
Now, we try dividing 124,124,425 by 3:
124,124,425 ÷ 3 = 41,374,808.3333
If the quotient is a whole number, then 3 and 41,374,808.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 124,124,425 | |
| -1 | -124,124,425 |
Let's try dividing by 4:
124,124,425 ÷ 4 = 31,031,106.25
If the quotient is a whole number, then 4 and 31,031,106.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 124,124,425 | |
| -1 | 124,124,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 83 | 205 | 415 | 1,025 | 1,459 | 2,075 | 3,403 | 7,295 | 17,015 | 36,475 | 59,819 | 85,075 | 121,097 | 299,095 | 605,485 | 1,495,475 | 3,027,425 | 4,964,977 | 24,824,885 | 124,124,425 |
| -1 | -5 | -25 | -41 | -83 | -205 | -415 | -1,025 | -1,459 | -2,075 | -3,403 | -7,295 | -17,015 | -36,475 | -59,819 | -85,075 | -121,097 | -299,095 | -605,485 | -1,495,475 | -3,027,425 | -4,964,977 | -24,824,885 | -124,124,425 |
